Procedure

In practice, the reactants and reactions are produced by mixing bulk quantities of sodium chlorite and lactic acid. In practice, three parts of sodium chlorite at a concentration of 26% by volume are mixed with one part of lactic acid at a concentration of 88% by volume which is a food grade of lactic acid. The 26% by volume of sodium chlorite and 88% by volume of lactic acid are commonly commercially available bulk quantities of these compounds and are generally provided to industry commercially in either drum lots or bulk quantities for example tank cars or tank trucks. Furthermore, note in the above reaction Number 1. that citric acid, HOC(CH2COOH)2COOH, may be substituted for the lactic acid to produce a salt of citric acid and chlorous acid in an aqueous solution.
